Vapor–liquid equilibrium data and their correlation for binary systems consisting of ethanol, 2-propanol, 1,2-ethanediol and methyl benzoate

Isobaric vapor–liquid equilibrium data for the systems ethanol+1,2-ethanediol, ethanol+methyl benzoate, 2-propanol+1,2-ethanediol, 2-propanol+methyl benzoate and ethanol+2-propanol were measured at atmospheric pressure (0.1013 MPa) with a CP-I dual circulation vapor–liquid equilibrium still. The results of the correlation of the experimental data with three thermodynamic models, DORDF, UNIQUAC and NRTL, were compared.
